That $6700 is a $5000 upgrade over a base model Macbook Pro.
$5000 in US Treasuries (currently at 4.89%) yields $244.5/yr. That's more than enough to cover the annual Claude Pro subscription ($200/yr) which includes Claude Code with lots of Sonnet usage (far better than Qwen 3.6)
I think the argument isn't that local is cheaper - it's that local is doable and delivers unparalleled privacy.
And your government can’t take it away on a Friday afternoon.
